How the mobile sketch works: The brain of the system is really on the arduino or the web page the phone requests. . . The phone just passes any data it sees back and forth. . . For the phone app to run, it needs the URL of a server and the path to a

Let’s add a DS1307 real-time clock to our Freetronics Arduino-compatible board. Updated 18/03/2013 Now and again I find myself making another kind of clock or timing device using the Arduino system, and each one has been making use of the Maxim DS1307 real-time clock IC. However every time another clock is being worked on, my DS1307 real-time

what: a 5*5 rgb led matrix, made with arduino and lpd6803 based leds from adafruit. with an pir sensor, it goes on if it detects movements and a ir distace sensor, 1 animation shows the distance you have from the sensor :). why: because its beautiful and cool 😉 my spelling: well, sorry if i

The Arduino Wireless shield allows your Arduino board to communicate wirelessly using Zigbee. This documentation describes the use of the shield with the XBee 802.15.4 module (sometimes called “Series 1” to distinguish them from the Series 2 modules, although “Series 1” doesn’t appear in the official name or product description). A Simple Example You should be able

This tutorial will describe a way of controlling an iPod remote, and thus, an easy way of getting some music and sound out of your Arduino project. The remote we used was an unofficial remote I found on the worldwide auction site for around 10 USD, an opto-isolator can be found in your local electronics

Background and motivation Two factors inspired this project: my struggle to wake up in the morning and my enjoyment of collecting and graphing data from daily tasks. My main problem with waking up in the morning is that feeling of grogginess along with an intense desire to sleep more. However, I’ve noticed that sleeping without

The title “MultiMovEDIA” does not mean much – if anything – at first sight. However, looking at more carefully, we can see it is a composition of two words: “Multimedia”, referring to the information content and the channels it uses (text, image, sound), and “Move”, meaning movement. This project incorporates movement and dynamics into the
This simple instructable will show you how to make a nightlight out of a translucent container, a bottle of tonic water, an Arduino, and ultraviolet LEDs. If you’ve ever played with a black light, you’ve noticed that some substances glow brightly under these lights. In this case, we’ll be using tonic water because it contains

This example shows you how to read analog input from the physical world using a potentiometer. A potentiometer is a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage through a potentiometer and into an analog input on your Arduino, it is possible to measure the amount of

When the button is pressed in this example, a text string is sent to the computer as keyboard input. The string reports the number of times the button has been pressed. Once you have the Leonardo programmed and wired up, open up your favourite text editor to see the results. NB: When you use the
